IPOB-A-TIQN' GF NEWT J LASTING Application filed November 16, 1931,Serial No.

This invention relates to lasting machines for use in the manufacture ofshoes, and more particularly to machines having wipers for wiping themarginal portion of an upper int-o lasted position about an end of ashoe and means for driving fastening-s to fasten the upper in lastedposition. The invention is herein illustrated as applied to a machinefor lasting the heel ends of shoes, of the same general type as thatdisclosed in Letters 0 Patent No. 1,583,044, granted on May 4, 1926,

upon an application of C. H. Hoyt and pro vided with upper-fasteningmeans of a type more particularly disclosed in Letters Patent N o.l,852,0l'5, granted on April 5, 1932, upon an application of J. G. Jorgensen. It is to be understood, however, that the invention is notthus limited in its applicability.

In accordance with the disclosure of the last-mentioned Letters Patentthe upperfastening means comprises drivers movable in directionssubstantially perpendicular to the plane ofthe wipers to drive tacksthrough the upper into the shoe bottom, and means forholding the tackswith their shank portions inclined inwardly away from the edge of theshoe bottom when they are in positions to be driven so that they enterthe shoe in suchinclined directions when they are driven. An object ofthe present invention among others, is to provide in an organization ofthat general character improved means for holding or controlling thetacks or like fastenings -whichw-ill be simple in construction, unlikelyto get out of order and readily accessihle when desired. For thepurposes in view the tack-holding means herein shown comprisesspring-pressed members arranged to suspend the tacks by their heads withtheir shank portions inclined as above described and yieldable to permitthe heads of the t acks to pass as the tacks are driven, theseme-mbers,as illustrated, consisting of balls arranged to extend part way onlyacross passages through whichthe tacks are driven and to engage theheads of the tacks at the sides thereof that are farthest from the edgeof the shoe bottomwhen the tacks are in-positions to be-driven. Theconstruction shown comprises upper-fastening mechanisms that ivraonrnn575,30 and in. Great Britain Decemberfl, 1930..

are movable inwardly over the shoe bottom w1th the wipers in the samegeneral manner as dlsclosed in the last-mentioned Letters Patent, andthe tack-controlling members" are pressed yieldingly into the paths ofthe tacks in directions substantially opposite to. the directions ofclosing movement of the respective wipers over the shoe bottom. Thesemembers, moreover, as illustrated, are mounted in openings thatextend tothe sides of the different 7 I other across the shoe bottom in thewiping operation, so that they are readily accessible at any time.

In accordance with a further feature, the invention provides improvedmeans to adapt, the machine to operate on shoes of different sizes. Forthis purpose the wipers herein shown have each a readily detachable endportion provided with a wiping face forming an extension of the wipingface of the rest of the wiper and provided with means for supporting oneof the upper-fastening tacks in position to be driven.

The above and other features of the invention, including also novelmeans for supporting the heel band with which a machine of theillustrated type is customarily provided, and various novel details ofconstruction and combinations of parts, will now be more particularlydescribed by reference to the accompanying drawing and pointed out intheclaims.

As more fully disclosed in the above-men tio-ned Letters Patent, themachine in which the invention is herein illustrated as emor PATERSON,new Jnnsn A son;

bodied comprises a pair of wipers 10 formed to embrace the heel end ofan upper and movable to wipe the marginal portion of the upper inwardlyinto lasted position over a sole or insole on a last. These wipers aresupported on a slide 12 which is movable to advance them bodilylengthwise of the shoes and on which they are guided for swingingmovements about an axis extending heightwise of the shoe to close theminwardly toward each other laterally of the shoe. For imparting theswinging or closing movements to the wipers there are provided slides14, one for each wiper, mounted on the frame of the machine formovement-s laterally of the shoe, each slide having an end portion 16provided with a slot 18 in which is mounted a roll 20 carried by theadjacent wiper. The slots 18 extend lengthwise of the shoe to permitadvancing movement of the wipers relatively to the slides 14. Each ofthe slides 14 carries a rack bar 22 engaged by a pinion 24 which isengaged and operated by a curved rack 26 formed on one end of abell-crank lever 28 pivoted at 30 on the frame of the machine, the otherend of this lever having thereon a curved rack 32 engaged and operatedby a rack bar 34. The construction shown comprises means more fullydisclosed in a copending application of Fred Ricks, Serial No. 562,083,filed on September 10, 1931, for imparting to the wipers first advancingmovement lengthwise of the shoe without any closing movements, thensimultaneous advacing and closing movements, and thereafter closingmovements only to complete the overwiping operation. For this purposethe two rack bars 84 are carried by a wlper closing slide 86 which isoperated independently of the wiper-advancing slide 12, and on these twoslides are mounted rolls 38 and 40 respectively which are engaged andoperated by a cam (not shown) to 1mpart to the wipers movements in theabove-mentioned order, as

disclosed in said Ricks application.

For fastening the heel end of the upper in lasted position the machineherein shown is provided with upper-fastening mechanisms associatedrespectively with the different wipers 10 and movable with the wipersinwardly over the shoe bottom in the same general manner as disclosed inthe above-mentioned Letters Patent No. 1,852,015, each of the mechanismsincluding a plurality of tack drivers 42 movable in directionssubstantially perpendicular to the plane of the wipers to driveupper-fastening tacks through the wipers into the shoe bottom, togetherwith means for holding the tacks with their shank portions inclinedinwardly away from the edge of the shoe bottom when they are inpositions to be driven. For positioning and controlling the tacks, inaccordance with one of the features of the present invention, each wiper10 is provided with an upstanding portion or flange 44 curved similarlyto its wiping edge and in which are formed a plurality the wipers and inalincment with driver guide passages 48 formed in a block 50 which issecured on the wiper in the same general manner as disclosed in thelast-mentioned Letters Patent. Formed also in each flange 44 are aplurality of cylindrical openings 52 (Fig. 3) spaced above the wipingface of the wiper and extending from the different respective tackpassages 46 to the concave side of the flange which faces the flange 44of the opposite wiper across the shoe bottom. Mounted in each of theopenings 52 is a small steel ball 54 which is snugly guided in theopening and is arranged to extend part way only across the tack passage46 to engage the head of the tack at that side thereof which is farthestfrom the edge of the shoe bottom when the tack is in position to bedriven and thus to suspend the tack by its head with its shank portioninclined inwardly away from the edge of the shoe bottom, as illustratedin Fig. 8. The extent to which the ball may thus project into the tackpassage is limited by a reduction of the bore of the opening 52 at theend of the opening next to the tack passage. The diameter of the ball issuch that when it is thus positioned a portion of it projects also fromthe concave face of the flange 44. The balls that are carried by eachwiper are pressed into the tack passages in directions substantiallyopposite to the direction of closing movement of the wiper and itsassociated fastening mechanism over the shoe by a series of dependingspring fingers 56 formed on a. comb-like member 58 bent in a concaveform and secured to the concave face of the flange 44. When the tacksare driven by the drivers 42 these fingers yield to permit the heads ofthe tacks to pass the balls 54. It Will be understood that each ball,while obstructing the tack passage sufiiciently to prevent the tack fromfalling through it by gravity, affords on its rounded surface merely asingle point of support for the lower surface of the tack head at theside of the tack which is nearest the concave face of the flange 44, sothat the tack is suspended by its head in an inclined position with itspoint just above the lower face of the wiper and in contact with thatside of the tack passage 46 at which the ball is located.

It will be evident that the above-described construction is simple tomanufacture, durable and not likely to give any trouble by reason of anobstruction in any of the tack passages. The balls 54, moreover, arereadily accessible, since all that is necessary if it is desired toremove or replace any of them is simply to remove the appropriate springmember 58.

To adapt the machine to operate in the wiper 10, in accordance ture ofthe lnvention,

is attached and rib 62 between best manneron shoes that. dilfer widelyin size. with considerable. corresponding variae tions in the lengths ofthe heel seats, each with. a. further. feais-provide dwith a readily.detachable end portion 60 (Fig. 4) located at the end. thereof whichisfarthest from the extreme end. of the shoe and pro? vided with meansforsupporting one of the tacks in position to be driven. Each detachableend portion 60 has a wiping face that forms an extension. of the wiping.face of themain portion. of thewiper to which. it has a horizontallyextending which and thelower. part of the end portion the main portionof the wiper extends to hold the difierent portions in verticallyfixedrelation to each other. Thereis also a tongue (Seton therib 62 whichinter? looks with a groove in the block to hold the different portionsin fixed relation to each other with respect to movement laterally ofthe shoe while permitting the endportion to be detached by sliding it ina forward direction. To hold the end portion 60 in place there isprovided a latch 66 which is pivoted on the block 50 within a recess inthe block and may be turned either into or out of a notch formed in therib 62. The latch has a head 68 thereon accessible to the operator andprovided with a slot adapted to receive a screw driver whereby the latchmay be turned. Eachdetachable end portion has a flange 44 thereon whichserves as an eXtension of the flanged l and is provided with a tackpassage 46 in alinement with a corresponding driverpassage 48 in theblock 50. There is also a ball 54 and a spring 56. which perform thefunctions of the corresponding:

parts on the main portion of the wiper, the spring 56 being fastened tothe front face of the end portion 60 and extending rearwardly intoposition to control the ball 54: as illustrated in Fig. 2.

The machine herein shown, similarly-to that shown and described in thepreviously mentioned Letters Patent No. 1,583,044, is provided with aheel band supported near its forward ends by clips 72 on rods 74 in suchav manner as to permitrelative sliding movements lengthwise of the handbetween the clips and the end portions of the band as the band is closedaround the heel end of the shoe. The present invention further providesadditional means for supporting the end portions of the band againstdownward tipping movement such as might result from the tendency of thewipers to tip the shoe when they first meet the heel end of the shoe.This additional meanscomprises blocks 76, secured on the outer faces ofthe end portions of the band between its upper and lower edges andprovided with ribs 78 which are slidable in directions lengthwise of theband in grooves formed in blocks 80 which are fast on the rods 74. Bythese riband groove connections the forward ends .of the band are ad:ditionally supported against downward movement with provision forrelative move ment lengthwise of the shoe between the blocks 76and 80 asthe end of the shoe.

It is to be understood that in its more general aspects the invention isnot limitedtoan organization in which the tack drivers. aremovableinwardly over the shoe bottom with the wipers, as herein shown,nor in which the drivers are movable perpendicularly to the plane of thewipers to drive the tacks; nor limited to an organization for drivingfastenings in the form of tacks.
